Letters Patent No. 105,284, dated July 12, 1870.

'KNEE-LEVER FOR MELODEON OR ORGAN-SWELL.

The Schedule referred to in these Letters Patent and making part of thesame.

Knee-Lever for Knee-swells for Organs and Melodeons, which I verilybelieve has never before been vknown or used, and that the following isa full and exact description of the same, reference being had to theaccompanying drawing and the letters of reference y marked thereon.

The ordinary way of constructing a knee-lever is by attaching it by ahinge to the frame of the organ, and having it so adjusted that, whenopened out, it rests against `the lever that operates vthe swell-valve,]1, and, when turned back out of the way, it has no connection with thelever; By this arrangement it is evidentthatit can onlyope1ate the leverwhen in one position, but by my invention the knee-lever is hin ged tothe lever that operates the swell-valve in such a way that it can vbeturned out or in, and 'yet be'v used at any time or position to operatethe valve.

Figur'Z represents the front of the organ or melodeon, with the coverremoved, to better show the po stion of the lever B, that works theswell-valve F, by' means of the connections D C, the L-shaped lever E.

To the lower end ofthe level' B the knee-lever H K is hung by a hinge,S, (see Figure 1,) in such a manner that, when notin use, it can beturned back under the action out of the way. 'Ihe position, when turnedback, is shown at fig. 1, and dottedlines lig. 2.

Figure 3 represents a side view'ot my knee-lever `when the salue isturned out, showing the hinge at S,

the edge of the lever B, and the screw O, by which the lever B isattached to the action M.

It will be seen by g.1 that, although the knee lever H K is turned backunder the action, that it is still attached to the lever B, so that atouch ot' the hand or knee at K will operate the lever B inthe samemanner as if H K was turnedout, as shown at fig.2.

lhe dottedllines,lg. 2, `shows the knee-lever H K turned-back in theposition of g. 1, and it will be seen that, in that position, the leverB can be equally well operated.

NVhat I claim as my invention, and desire to secure by Letters Patent,is as follows, to wit:

The construction of the knee-lever H K, attached to the leverB, by meansof the hinge or joint S, when constructed as described, 'for thepurposes set forth.
